Where do tears come from?
They come from a structure called the Lacrimal Gland locate in
the sperior lateral part of the eye socket. Tears are distibuted
onto the eyeball by the Lacrimal Ducts. They are then spread by the
eyelids which eventually push the fluid Medially towards the
Lacrimal lake (technical term for the tear drop often seen under
the eye). From the lacrimal lake the Cannaliculi (what most people,
including the answer above, see as the tear ducts) drain the fluid
into the Lacrimal sac from which the Nasolacrimal Ducts carry the
fluid into the middle meatus of the nose.
